Vitreoretinal surgery aims to restore the structural relationships of the posterior segment of the eye, with the possibility of partial or complete restoration of visual functions, and imposes certain requirements to the anesthetic support of operations. These are injuries, operations length, age, and concomitant pathology of organs and systems of patients. In this regard, there is a recent tendency to use different pharmacological groups as adjuvants to local anesthetics to enhance or prolong their analgesic effect. Purpose to evaluate the effectiveness of dexmedetomidine as an adjuvant in retrobulbar blockades. Materials and methods. Retrobulbar block bupivacaine with dexmedetomidine at a dose of 0.25 mg/kg was performe in the 1st group (n = 22), retrobulbar block was performed with a mixture of bupivacaine in the 2nd group (n = 22). Changes in hemodynamics at the stages of surgery were evaluated. To assess the oxidative status, the evaluation of the redox coefficient (FORT/FORD) was conducted before and after the surgery. The level of comfort of the operation by the surgeon and the patient. Assessment of pain was performed by a VRS in the points. Results. In patients of the 1st group the decrease in SAD was more pronounced and persisted throughout the entire period of surgical treatment. 54.5% of patients of group 1 and 18% of group 2 had no pain 8 hours after the surgery. 82% of patients of group 2 reported moderate pain that required medication (p 0,05). In patients of group 1, it increased from 0.45 0.5 to 0.62 0.2 (p 0,005) by 37% of the initial value, in patients of group 2, it was shown to decrease by 5% (p 0,05). In group 1, the comfort of the operation was estimated by ophthalmic surgeons as satisfactory in 77.3%, and in group 2 in 54.5% (p 0,05). Conclusion. The use of dexmedetomidine as an adjuvant of local anesthetics in ophthalmic surgery provides the necessary analgesia, hemodynamic profile of the patient, antioxidant effect and affects the quality of the surgeons work, which affects the duration of operations.

Purpose: To evaluate the efficacy and safety of peribulbar anesthesia during strabismus surgery. Methods: Medical records of patients undergoing strabismus surgery and peribulbar anesthesia were reviewed. The overall efficacy of peribulbar anesthesia was evaluated as requirement of supplemental peribulbar anesthesia, impossibility to perform eye muscles surgery due to inadequate efficacy of the block and peribulbar block complications that occurred up to 6 weeks postoperatively. Presence of oculocardiac reflex (OCR) and presence of decreased visual acuity and afferent pupillary defect postoperatively were reported. Results: A total of 510 patients comprised our study group. The total amount of peribulbar injections was 717. Four patients (0.7%) required supplemental injection in the superonasal quadrant. Five of 510 (0.9%) required an anesthesiologic intervention with intravenous atropine. Eighty patients of 510 (15.6%) complained about transitory complete ptosis and/or amaurosis postoperatively. No complications were observed up to 6 weeks postoperatively. Conclusion: Peribulbar anesthesia was an effective and safe option during strabismus surgery in adult patients.

Abstract Background: Despite of the risk of postoperative intolerable pain perception (PIPP), vitreoretinal surgery (VRS) requires general anaesthesia (GA) in selected patients. Intraoperative use of opioid analgesics (OA) during GA carries the risk of postoperative nausea and vomiting (PONV). The surgical pleth index (SPI) optimises the intraoperative titration of OA. Regional anaesthesia techniques are combined with GA to minimize the intraoperative use of OA. We evaluated the benefit of preventive analgesia techniques combined with GA using SPI-guided fentanyl (FNT) administration on the incidence of PONV, oculocardiac reflex (OCR) and PIPP in patients undergoing VRS. Methods: One hundred and five patients undergoing VRS were randomly allocated to receive either GA with SPI-guided fentanyl (FNT) administration alone (GA group) or with preventive topical 2% proparacaine (topical anaesthesia (TA) group) or preoperative peribulbar block (PBB) using 0.5% bupivacaine with 2% lidocaine (PBB group). Fifteen patients were excluded due to problems with postoperative SPI measurement. Results: Preventive PBB resulted in intraoperative reduction in FNT requirement, with no influence on perioperative outcomes. Intraoperative SPI-guided FNT administration during GA resulted in OCR in 7.78%, PONV in 10% and PIPP in 13.5% of patients undergoing VRS. Intraoperative SPI-guided FNT administration blunted the perioperative effect of preventive PBB and TA in terms of the presence of PONV, OCR and PIPP.Conclusions: The utility of SPI-guided FNT administration during GA eliminated benefits of preventive analgesia with PBB and TA following VRS. We recommend using intraoperative SPI-guided FNT administration during GA to reduce the presence of OCR, PONV and PIPP following VRS. Trial registration: The trial was approved and registered by The Ethical Committee of Medical University of Silesia on 29th of September 2015, as well as the project was registered in the Clinical Trial Registry (SilesianMUKOAiIT2, NCT02973581)Key words: vitreoretineal surgery, general anaesthesia, peribulbar block, topical anaesthesia, surgical pleth index.
